PUZZLE.

Specification of Letters Patent.

Patented Nov. 12, 1907.

Application filed January 31,1907. Serial No. 354|999| To all whom it may concern:

Be it known that f, EDMUND O. MAoAn'rNnY, a citizen of the United States, and resident of Philadelphia, in the county of Philadelphia and State of Pennsyl- Vania, have invented a certain new and useful Puzzle,

of which the following is a specification.

The principal objects are to provide a puzzle which shall be popular, diverting and quaint and whereof the device shall be self-contained, neat, durable and comparatively inexpensive to manufacture and which shall further possess the qualities of being capable of use as an advertising medium.

To these and other ends the invention resides in the novel puzzle and apparatus hereinafter described and finally claimed.

The nature and characteristic features of the invention will be more fully understood from the following description taken in connection with the accompanying drawings forming part hereof, and in which Figure 1, is a top or plan view of an egg embodying the puzzle. Fig. 2, is an elevational view of the same. Fig. 3, is a central sectional view of the same with the interior parts thereof in elevation. Fig. 4, is a plan view of the egg with the upper casing thereof removed,

and Figs. 5, 6, and 7, are sectional views illustrating the interior regulating device of the egg, and which will be referred to hereinafter.

Inthe drawings, the puzzle is shown to consist of v a two-part shell of any preferable material, for instance, celluloid. The casing a, is shown as being somewhat pointed and the casing b, as being more rounding and having designated thereon a pictorial representation of a compass 0. These two parts of the shell are adapted to snugly fit together in order to present a neat appearance. This is accomplished by slightly offsetting the upper rim of the part a, to form a concentric seat (I, for the lower edge of the part 7). Within the egg is a generally bulb-shaped receptacle 0, that rests at the pointed end of the egg and terminating in a tubular 4i stem f, the upper extremity of which is slotted at g. The bulb and stem may readily be made of glass, and

the stem is adapted to carry a paper or other disk 11,

that is constructed to tightly fit the interior wall of the casing a, of the egg. Superposed upon the disk h, is a 4 skeleton-like structure, as of paper, comprising a pair of intercommunicating chambers '17, and j, covered as by a housing k, I being a by-passage between the said chambers.

By referring to Fig. 4, it will be observed that the partitions of the above structure register with the four points of the compass, and that the partition m, for the sake of illustration is shown as being in alinement with the western point thereof. The fact that this particular partition is so arranged, gives the person working out the puzzle, the key to its successful manipulation. It is also important to the successful working of the puzzle that the slotted portion 9, of the stemf, does not reach below the top of the passage 1. Contained within the above described parts, which may be termed the regulating device, is a suitable balancing medium or weight such as mercury, sand, shot or other material, mercury, however, on account of its lively disposition being preferable.

The object of the puzzle is to stand the egg upon its pointed end. Referring now to Fig. 6, the mercury assuming that such is being used, is all retained within the inter-communicating chambers 11 and j, and in this relation to the egg the weight of the mercury will cause the device to fall when placed in upright position. When, however, the egg is held so that the angle is approximately as represented in Fig. 7, and is revolved in a clockwise direction once from west on the compass upon its axis or until the partition m, which it will be remembered is in alinement with W, of the compass, has collected all the mercury in the chamberj, and the egg then quickly upturned so that the mercury will flow into the stem and bulb, guided by the partition m, the egg may be stood upon its end.

Having thus described the objects and nature of my invention, what I claim as new and desire to secure by Letters Patent is l. puzzle comprising an egg-shaped two-part shell and a regulating device comprising a bulb-shaped receptacle terminating in a hollow stem and adapted to rest at the pointed end of the egg said stein being slotted at its upper extremity, a disk carried by the stem and adapted to snugly fit the egg interior, means equipped with communicating chambers superposed upon said disk whereof one of said chambers has communication with the aforesaid slotted tube, and fluid balancing means as mercury for the regulating device.

2. A puzzle comprising an egg-shaped two-part shell having designated thereon a representation of a compass that acts as a guide, and means within the shell comprising a regulating device with a mobile balancing medium for manipulating the so as to stand it upon its end.
